Publication Date: February 2007; © 2008

A. P. Trujillo

Major improvements to Essentials of Oceanography, 9th Edition include:

bulletThe "Key Questions" at the beginning of each chapter are tied directly to the highlighted "Concept Statements" imbedded within the text and serve to focus attention on key concepts
bulletIcons in the text that link to a suite of new geoscience animations, which are state-of-the-art computer animations that have been created by Al Trujillo and a panel of geoscience educators to help students visualize some of the most challenging oceanographic concepts
bulletNew geoscience animations that have been specifically designed for this edition are:
bullet Formation of Seamounts/Tablemounts and Stages of Coral Reef Development
bullet How Calcareous Ooze Can Be Found Beneath the Calcite Compensation Depth (CCD)
bullet Ekman Spiral and Coastal Upwelling/Downwelling
bullet Interference Patterns in Waves
bullet The Deep Scattering Layer (DSL)
bulletUpdating of information throughout the text to include some of the most recent developments in oceanography such as the recent Indian Ocean tsunamis and Hurricanes Katrina, Rita, and Wilma
bulletFeature boxes—several of them new—are organized around the following three themes:
  1. Historical Features: these boxes focus on historical developments in oceanography that tie into chapter topics
  2. Research Methods in Oceanography: these boxes highlight how oceanographic knowledge is obtained
  3. Oceans and People: these boxes illustrate the interaction of humans and the ocean environment
bulletAddition of several new tables that better organize and summarize important data
bulletAddition of an extensive array of updated photos and illustrations to improve the illustration package and make the figures more consistent throughout
bulletExpanded end-of-chapter "Review Exercises" and "Critical Thinking Questions" sections to help students test their knowledge
bulletAll text in the chapters has been thoroughly reviewed and edited in a continued effort to refine the style and clarity of the writing
